Error 1603

Anonymous — Sat, 14 Mar 2020 02:21:22 GMT

Hi! I'm at my wits end.

I'm a student trying to install AutoCAD 2020 on my laptop. I had already successfully installed it on my PC. As I understand it, I can install it on up to 2 devices.

I keep getting error 1603 and I've already tried:
- turning off anti virus
- clearing temp folders

- ccleaner

- disk cleanup

- turning off firewalls (anti virus & windows defender)

- installing using Autodesk App
- installing via the download now method

- multiple restarts

And I always get to 5 out of 14 during install but it always rolls back to 6/14 then 7/14 then hangs there then stops.

I also tried AIDA but I don't think it's working?

If anybody could help, please do.

If it helps, I finally found the installation log...

This worked for me. Find the C:\autodesk folder and rename it or delete it. Now try installing again. HTh

This didn't work for me. Any other possible fixes? Microsoft Fixit cannot identify the problem either.

UPDATE:
I followed these steps: https://knowledge.autodesk.com/customer-service/download-install/remove-products/clean-uninstall

And I also ran as an admin on cmd "sfc /scannow", rebooted and tried to reinstall. I even uninstalled my antivirus software (Avast & Malwarebytes) and the installation still failed...

This finally worked for me!

If the above doesn't help and the product installation still fails, setup Autodesk Desktop Licensing Service to start from local system account.

Type services.msc in Windows Search and hit Enter key.
In Services console locate Autodesk Desktop Licensing Service and double-click on it.
Under General tab, click Stop to stop the service .
Under Log On tab, below Log on as: select Local System account, and hit OK.
Go back to General tab and click Start to start the service.
Try Autodesk 2020 version product installation again.

Just want to comment that until I switched the "Log on as" for "Autodesk Desktop Licensing Service" from "This account" to "Local System account", nothing worked. Thanks, @Anonymous.

Maybe I missed it, but I combed through all the .log in %LOCALAPPDATA%\{Temp,Autodesk\ODIS}, and didn't see any hint of this being the problem.

As an aside, a lot of the .log or .LOG files in %LOCALAPPDATA%\Temp are in UTF-16, so I had to use "iconv" for "less".

I enabled the MSI*.LOG through the "regedit" method. There is no "Logging" in "gpedit". It worked for a while, then it stopped working. I don't know why. Autodesk's .msi cannot be invoked with "msiexec", so I couldn't use the "/l*vx" option to try to figure out what went wrong.

Sorry, I forgot to mention that my problem was with Revit LT 2023, but I tried 2022 and 2021 also. Fusion 360 does not have this problem.

You'll need to share a screenshot of the actual error pop-up you receive, plus a copy of your installation LOG file the program created for you (it's in your Windows login TEMP folder), and confirm if you've engaged your I.T. person yet to help and if your login is at the local admin or hire level on your PC/Laptop.
